Endymion pressed his shoulder into the steel bars, pushing with steady pressure so the gate would swing gently rather than clang open. He had waited for just the right moment when the guards would be furthest from this hidden gate. Serenity had given him the key to the lock, but it would still mean death if he was caught entering the palace garden.
Endymion was an earthling and the current political tension between the earth and the moon meant that relations between earthlings and lunarians were all but forbidden. And the lunar crown princess was no exception. Still, his princess was worth everything, even his life. With one final push, the steel gate swung open and he went in to his love.
